Figure 5.4 : Dual patch recordings between adjacent rods in the whole retina. (A) Example
current flow in the driver cell in response to voltage steps from -120 to +20 mV. (B) Example
current flow in the follower cell held at -40 mV in response to driver cell command voltage
changes. (C) I-V relationship for dual patch recordings showing initial (red) and steady-
state (black) currents. Average network resistance between all cells recorded was 890 ± 10
MΩ (SEM) from the initial current, and 1120 ± 13 MΩ from the steady-state current. Data
comes from 24 trials (11 pairs + 2)
